BOAT.

Application filed July 6,

To all whom it may concern: 7

Be it known that I, JOHN MoLEoo, a citizen of the United States, residing at Downing, in the county of Dunn and State of Wisconsin, have invented certain new-and useful Improvements in Boats, of which the following is a specification, reference being Other objects and advantages of the invention will appear in the further description thereof. 7

Referring to the accompanying drawing forming part of this application and in which like reference characters indicate like parts:

Figure 1 is a longitudinal vertical central sectional view of a boat embodying my invention,

Figure 2 is a top plan view, and igure 3 is a transverse sectional view, somewhat enlarged, on the line 3- 3, Figure 2.

The hull 1 of the boat intermediate of the after bulkhead 2 and the forward bulkhead 3 is circular in crosssection and of barrellike construction, that is to say composed of a plurality of spaced circular hoops 4, upon which the outer wall, or boards if constructed offwood, are securely fastened. The bottom portion may be reinforced with a floor, as indicated at 5, or in any desired manner. Approximately one-sixth of the diameter of the hull inwardly of the sides thereof is installed a longitudinal bulkhead 6 it being secured to spaced fractional bulkhead sections 7, that is to say there may be any desired number of fractional bulkhead sections upon either side of the hull, forming a plurality of air chambers intermediate of same and the bulkhead 6 and the skin of the hull.

In approximately the center of the upper 1923. Serial No. 649,910.

deck of the hull is formed the cock pit opening or hatch indicated at 8, it being surrounded by suitable coaming. Upon the cylindrical hull portion of the boat is formed the flat deck indicated atv9 having vertical side walls 10 extending downwardly approximately on a plane tangent with the I side walls of the cylindrical portion, thus forming approximately triangularly shaped air spaces 11 upon the upper opposite corners of the hull and insuring a hull construction that can only remainright' side up either on or under the water. I

The how 12 of the boat is of separate construction and made of any form v desired. preferably with an overlapping flange portion indicated at 13 which is securelvriveted or-bolted externally of the forward end of the hull 1. This bow section isdesigned to be air tight, forminga buoyant compartment for the forward end of the vessel. The" after or stern end 14 is of like separate construction and may be attached to the stern of the hull in the same manner, it being pro" vided with a tunnel or shaft tube 15 for reception of the propeller shaft, if the same a buoyant section at the stern of the-boat.

From the foregoing it, is evident that I be a power driven boat. This stern pQI'tlOIi' a 14 is also of air tight construction forming haveproduced a form of boat construction the individual parts of which are uniform for a major portion of the structure, thus V lessening the costof construction, and one that when built would be exceedingly seaworthy and safe. While I consider the most practical form of such boat as being with-7 I claim and desire to secure by 'Ifetters Patent, is:

V A boat comprising in combination a main hull substantially tubular in fonn through I out, 'a transversebulkhead. at either endof said hull, a'separable stern portion compris ing an air tight chamber, a separable bow portion comprising an air tight chamber, cellular air chambers longitudinally of and i Within either side of the main hull, a Hat In testimony whereof I hereunto afliX my deck over the nialn hull having depending; signature 1n the presence of two witnesses. side and end walls attached to the Walls of the hull forming longitudinal air chambers JOHN MOLEOD' above the last mentioned air chambers, and a Witnesses: cock pit Within the hull, substantially as S.
